IIS socket problem?

[lars-sh]

I'm working on simple "HOWTOs" to run unoconv (from SVN) via PHP on Ubuntu 11.10 (using Apache 2.2) and on Windows (using either Apache 2.2 or IIS 7.5).

On Apache 2.2 things go just right, but on IIS 7.5 unoconv starts successfully (I see the python.exe/soffice.bin/soffice.exe processes), but the request never ends. Finally I aborted the soffice.exe process and got some output.

<?php
header('Content-Type: text/plain; charset=utf-8');
$ubuntu = '"/usr/bin/python" "/var/www/unoconv" --format="pdf" --verbose --verbose --verbose "/var/www/test.odt" 2>&1';
$windows = '"C:\\Program Files (x86)\\LibreOffice 3.5\\program\\python.exe" "D:\\www\\unoconv" --format="pdf" --verbose --verbose --verbose "D:\\www\\test.odt" 2>&1';
echo shell_exec($windows);
exit;
?>

This result in $windows = "C:\Program Files (x86)\LibreOffice 3.5\program\python.exe" "D:\www\unoconv" --format="pdf" --verbose --verbose --verbose "D:\www\test.odt" 2>&1 creates the following output:

Office base location: C:\Program Files (x86)\LibreOffice 3.5

Do you have any idea what's the problem? Or maybe you could specify a range of problems, so I can check out things...

For me it seems to be a socket related problem. So does IIS require additional permissions here?

Okay guys, it's a permission problem with the IUSR account. Changing from Pass-Through-Authentication to a static user helps.
